Sudoku App
I've released a simple Sudoku Android app on the Play store. It generates Sudoku puzzles with unique solutions at a variety of different difficulty levels, as well as allowing the user to enter their own puzzle. It can provide hints by filling in single cells or the full solution using a backtracking solver.
Here is a link to the app in the Google Play store. If you download it, feel free to send feedback at [email protected]!
